    After one flight with my CS6 the other day I landed to change batts. When I went to start again the Hexa appears to have lost radio signal from my DX8 to the chopper. I'm getting a constant beeping sound (like a fire alarm) and the Satellite on the copter won't light up. I can see a red led light on both the FC and Navi board.
    * I see no brakes in Sat wire to FC. Solder connections look solid.
    * Sat is working. I plugged it into another receiver and it lit up.
    * I have not tried re-binding. Desperately, I might try this.

    Any other ideas?

    Jim is there a pattern to the beeping, like morse code? What is that pattern? A rebind would be the first thing you should try.

    Same thing happened to me a few weeks ago. The alarm is likely the no Tx connected alarm. Plug into MKTools and ensure that somehow the Tx is still set as Spektum Hi Res and not JR like mine got somehow changed to - a huge mystery still.

    If the FC/Rx fails to detect a transmitter, you'll get the Morse for the letter J : dit-dah-dah-dah. I called it the J-code for reasons you'll have to figure out. :)

    Or were you getting a continuous beep?

    Andy and Gary,
    "J" is for Jeeziz criest, why doesn't this thing work? It was a Morse code like thingy.
    Sooooo......I tried to rebind, but got no where. I tried another Satellite just for grins...and presto...the Hexa came back to life. How does a satellite go bad?

    Thanks for all your advice. This forum is the best.

    Actually it's J for "Just where did my Tx go?" :)

    Glad you found the problem. My guess is the satellite Rx decided that life wasn't worth living and went to satellite Rx heaven.....probably a component failure.... :)

    Andy.
